Question

我正在尝试为GIMP编写一个Python-Fu插件，但添加4个以上的输入参数（包括Image和Drawable参数）将导致脚本根本无法运行。我已尝试使用各种输入参数类型，它们都产生相同的结果。有没有人知道为什么会这样？我错过了一些明显的东西吗？

register(
"python_fu_guide_maker",
"Guide Maker",
"Creates guides with specified spacing.",
"MrKagouris", "", "2017",
"Guide Maker",
"*",
[
    (PF_IMAGE, "image", "Input Image", None),
    (PF_DRAWABLE, "drawable", "Input Layer", None),
    (PF_INT, "hspace", "Horizontal Spacing", None),
    (PF_INT, "vspace", "Vertical Spacing", None),
    (PF_BOOL, "percent", "By percent?", None)
],
[],
guide_maker,
menu="<Image>/Image/Guides"
)

下面是完整的，功能齐全的脚本，包括Python代码。

#!/usr/bin/env python

from gimpfu import *

def guide_by_num(image, hspace, vspace):
    imageHeight = pdb.gimp_image_height(image)
    imageWidth = pdb.gimp_image_width(image)
    if (hspace <= 0 or vspace <= 0):
        return                          # Input validity check.
    hGuides = int(imageHeight/hspace)   # Calculates the
    vGuides = int(imageWidth/vspace)    # number of guides.
    for i in range(2):
        pdb.gimp_image_add_hguide(image, i * imageHeight)   # Adds guides to
        pdb.gimp_image_add_vguide(image, i * imageWidth)    # image edges.
    for i in range(1, hGuides):                         # Adds the horizontal
        pdb.gimp_image_add_hguide(image, i * hspace)    # guides.
    for i in range(1, vGuides):                         # Adds the vertical
        pdb.gimp_image_add_vguide(image, i * vspace)    # guides.

    imageHeight = pdb.gimp_image_height(image)

main()

您必须在注册中使用整数默认值，而不是None：

[
    (PF_IMAGE, "image", "Input Image", None),
    (PF_DRAWABLE, "drawable", "Input Layer", None),
    (PF_INT, "hspace", "Horizontal Spacing", 0),
    (PF_INT, "vspace", "Vertical Spacing", 0),
    (PF_BOOL, "percent", "By percent?", 1)
],

GIMP Python-Fu脚本不能运行超过4个参数
